Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Processing external walls, such as painting, cleaning, or polishing, is a strenuous task that requires complex and risky operations due to the need for uniform application across large and varied surfaces.
Innovation Solution
A system comprising a suspended platform anchored to the structure, operably vertically moveable at a constant speed, and a positioning system that controls a predefined motion pattern for the working equipment, allowing continuous and uniform application both horizontally and vertically along the external wall, using diagonal and vertical movements to cover all segments efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual methods are used for processing external walls, then flexibility and adaptability are maintained, but labor intensity increases and work safety deteriorates
Solution Approach 1:
The system enables automated self-service processing where the suspended platform autonomously moves along the external wall and applies working equipment without continuous manual intervention. The platform integrates propulsion mechanisms, positioning systems, and working equipment that operate automatically, reducing labor intensity while maintaining safety through automation.
Solution Approach 2:
Manual mechanical operations are replaced by an automated mechanical system comprising a suspended platform with integrated propulsion, positioning, and working equipment. The platform uses mechanical drives, sensors, and control systems to automatically perform wall processing tasks, eliminating the need for workers to manually climb and operate on high walls.
2Productivity
If automated systems are introduced to reduce labor intensity, then productivity increases, but device complexity increases
Solution Approach 1:
The suspended platform is designed as a universal multi-functional system that can perform multiple wall processing operations (painting, cleaning, polishing) using different working equipment. This multi-functionality increases productivity without requiring separate automated systems for each task, thereby limiting the increase in overall system complexity.
Solution Approach 2:
The automated system is segmented into modular functional units: propulsion mechanism, positioning system, working equipment, and control system. Each module can be independently designed, maintained, and replaced, which manages device complexity while maintaining high productivity through coordinated operation of these segments.
3Manufacturing precision
If uniform application across large surfaces is required, then processing quality improves, but the time required for completion increases
Solution Approach 1:
The suspended platform maintains continuous motion along the external wall through integrated propulsion mechanisms, eliminating idle time between processing segments. The platform continuously applies working equipment to the wall surface while moving, ensuring uniform application across large areas without interruption, thereby maintaining precision while reducing total processing time.
Solution Approach 2:
The system dynamically adjusts the speed and motion of the suspended platform to maintain optimal processing conditions across varying wall surfaces. The positioning system continuously monitors and adjusts platform movement to ensure uniform application, adapting in real-time to maintain precision without sacrificing overall processing speed.
4Area of stationary object
If working equipment is applied to high walls, then coverage area increases, but access difficulty and operational risk increase
Solution Approach 1:
The suspended platform serves as an intermediary carrier that transports working equipment to high wall surfaces without requiring direct human access to dangerous heights. The platform is suspended from the structure and can safely reach elevated areas, enabling wall coverage of large areas while operators remain in safe locations controlling the system remotely or automatically.

AI summary
A system for applying working equipment onto an external wall of a structure. One system comprises a suspended platform anchored to the structure, operably vertically moveable at a constant speed along the external wall; and a positioning system arranged to determine and control a predefined motion pattern of the working equipment relative to the suspended platform, the positioning system mounted on the suspended platform. The predefined motion pattern is selected such as to allow continuous and uniform application of the working equipment horizontally and vertically onto the external wall during the vertical movement of the suspended platform along the external wall. The predefined motion pattern comprises a diagonal movement comprising a vertical component and a horizontal component, wherein the vertical component is equal and opposed to the vertical movement of the suspended platform.
